' INFLATION-VALVE.

To all whom it may concern:

Beit known that l, JOHN ESTEN KELLER,

` Jr., a citizen of the United States,4 residing at Litcheld, in the county of Litchfield and 4State of Connecticut, have .invented a new' and useful Inflation-Valve, of which the following is a speciiication.

forinlatable tires, 'and has for its object to'l provide Certain new and useful improvements i in the valve mechanism whereby the valve lelement is-y held against displacement in- Wardly through the tubular'valve-stem by the action of the inflo pressure or by reason of, t e mechanical unofthe'device with a pump.

It' is also ient remova airs. l A further Objectis to prevent entire displacement of the rim-enga 'stem-fastening means with the dust-cap should these. two elements become interlocked. y

, With these and other objects in view the present invention consists in the combination and .arrangement of arts, as will be hereinaftermore fully descri ed, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being n understood that changes in the form, proportion, size, and minor details may be made within the sco e of the claims without departing fromyt ev s irit or sacriiicing any of the advantages` of t e invention.

valve-tube.

valve is seated. `its clearly indicated in Fig. 2 of the drawings, it 'will'be noted that the internal projections 22 lconstitute stops to limit the downward movement of the valve, and thereby prevent displacement of the latter' through the lower open end of the The upper end of the valvetube is' revided with an internal and externally t readed.v nipple 27 for engagement with externally and internally threaded There is a closure for the open outer end ofthe nipple consisting of va tubular internally-threaded shank 28, for the reception of the upper threaded terminal 24 of the valve-stem 23, the upper end of the shank being provided with a head 29, adapted to close down tight against the nipple, as clearl sho-wn intliig. 1 of the drawings. In laddlitionto closingthe open top of the valve-tube the element .28 constitutes a valve holder or retainer to mechanically hold the valve seated, reason of the fact that the valve is drawn up snugly against the scat 20 when the head 29 .of the holder engages the nipple and the device is further rotated.

To enablel the'convenient removal ofthe -valveefrom the valve-tube, the lower end of .the stem 23 is projected below thevalve 25, as shown at '30, to afford a finger-grasp, whereby the valve may be forcibly drawn past the projections 2 2. By preference this projec- .tion 30 is threaded in order that the valve 'holder or retainer l28 may be fitted thereto whenthe valve-tube has been removed from the tubular/va'lvc-stem 1, so as to 'constitute'l a handlefor more conveniently removing the valve from the valve-tube. It willghere be explained that the bifurcating of the inner or vlower end of the valve-tuberenders the latter elastic to permit of the walls yielding sufficiently to enable the withdrawing of the valve past the projections 22. Y

lThe valvetube 17 is retained within the tubular stem 1 by means of a retaining-cap 31, which is internally. threaded to embrace the outer end of the stem 1 'and is provided.

at its outer end with an internal annular flange 32 to embrace the outer end of the valve-tube at the base of the nipple 27. To prevent rotation of the valve-tube within the tubular stem, said tube is provided withv lateral projections 33, designed to hereceived Within notches or seats' 34 in the outer end of.

@sacri the tubular valvesteml Similar means are employed to prevent rotation of the valve 25 within the valve-tube 17 and consists of opposite projections 35, which work in the slots 21 ofthe valve-tube.

The members 31 and 29 are housed and protected by means of a tubular cap "36,

which is closed et its outer end and embraces the outer end portion of the tubular stem 1, i

its open end portion being internally threaded for engagement with the externally-threaded ortion of the nut 9', the lower end of the cap eing desi ed to bear againsty the packingring 12 of t enut.

As the cap 36 and nut 9 become interlocked by frictionai contact and 'also by met the nut will be backed of of the stem 1 with the dustcap. To prevent entire removal of the nut with the dust-cap, there is provided a follower 37 in the nature of e. metallic ring loosely embracing the stern 1 between the nut 9 and the retaining-cap 31, the inner edge of the follower being provid ed with diametrically opposite flattened portihns 38 to engage the flattened faces of the stem, and thereby prevcntrotation of the washer. In view of the fact that the washer or follower 37 is slidable upon the stem and the nut 9 ie rotatable upon the stein independently .of the follower, the nut may be tightened against the rim of the wheel without removing the dustcap 36; the retaining-cap 31, and the follower. Furthermore, should the nut work loose it cannot come entirely off, for the reason that the follower 37 will contact withpthe retaining-cap 31, and thereby limit outward movement of the nut.

In Fig. 6 of the drawings I have shown the valve mechanism hereinbefore described applied to a slightlydifercnt form of tubular stem, which is designated 39, the outer end portion of the stem bein reduced, as at 40, so as to receive the retaining-cap 31 and have the outer periphery of the latter lie within the outer periphery of the stem 39, so as to permit of the cap 41 being threaded directly to the stem 39. With this form of stem any approved means may be employed for clampingV the same to the tire and rim.
